摘要
本文利用超声脉冲反射法,对人体血管壁声衰减特性进行了离体测量,给出了人体血管壁声能量衰减参数的测量值。这对超声在医学领域的应用以及超声连体非介入血栓消溶有着十分重要的意义。
The attenuate characteristic in human blood vessel wall was measured by the ultrasonic pulse reflection. The measurement value of ultrasonic-attenuate parameter in human blood vessel wall was obtained. Transmitting attenuate characteristic of ultrasonic wave in human blood vessel wall analyzed. The attenuation characteristic of ultrasonic wave in the living-things medium was found out by way of measuring transmitting characteristic inside blood vessel. It has the very important meaning for disappears and dissolution of the non-intervene thrombus under action of ultrasonic wave.
